class_docstr: Shuffling implements a shuffling algorithm. Items can be added to the shuffling buffer and removed in a
  different order as defined by the concrete shuffling algorithm. A shuffling buffer is intended to be used from
  a single thread, hence, not thread safe.
docstr: Checks the state of the buffer and returns whether a new item can be added to the buffer at the time.
  
  :return: A boolean indicating whether an item can be added to the buffer at the time.
